Default Codes for my LT4

Okay I went and pulled the codes off my car. I already put a new crank sensor on the car as it was pulling that code and still is. I cleared the codes but these are back.

Codes are:

P0118 - Engine Coolant Temp Ckt high input - Could someone elaborate on this?

P0335 - Crankshaft Position sensor A circut malfunction. -has a new crank sensor installed.

P0336 - Crankshaft position sensor A ckt rng perform.

P0443 - EVAP cntrl system purge valve C fault - I think that's part of emissions that was pulled off the car.

I would test the wires that run to the temp sensor and the cps. I would also try to find out if they are on the same circuit or not.
